• Experience designing, building, or automating test suites (functional, regression, integration) using at least one of these technologies: pytest/pytest-qt, Selenium, TestNG, Jenkins, Azure DevOps, GitLab CI/CD.
• Fluent in two or more programming or scripting languages, e.g.: C/C++, Python, PowerShell, Java, JavaScript, Bash.
• Hands-on experience using configuration-management and version-control tools such as: Git, SVN, TFS, Mercurial, Perforce.
• Formal education or professional experience in a relevant field: Cybersecurity, Electrical Engineering, Computer Engineering, Computer Science, Information Assurance, or a related discipline.

Nice To Haves

• Experience with cloud-native security platforms (e.g., AWS Security Hub, Azure Sentinel, Google Chronicle).
• Container and orchestration hardening - Docker, Kubernetes, OpenShift, and related security tooling (e.g., Falco, Aqua, Twistlock).
• Familiarity with AI/ML security concepts such as adversarial machine-learning testing, model-poisoning detection, and secure deployment pipelines.
• Hardware/firmware reverse-engineering - ability to analyze BIOS/UEFI, embedded firmware, or IoT devices (e.g., using Chipsec, Binwalk, Ghidra).
• Threat modeling & secure architecture design - expertise with STRIDE, PASTA, or MITRE ATT&CK for system-level threat analysis.
• Knowledge of compliance frameworks and standards - NIST 800-53, ISO 27001, IEC 62443, DoD RMF, or CMMC requirements.
• Automation & orchestration scripting beyond testing - creating custom CI/CD security gates, infrastructure-as-code security checks (e.g., Terraform, Ansible, Pulumi).
• Red-team leadership or mentorship experience - guiding junior analysts, conducting tabletop exercises, or managing multi-discipline assessment teams.
• Secure software development practices - static/dynamic analysis (e.g., SonarQube, Coverity), code-review tooling, and secure coding standards (CWE, OWASP).
• Project-management or Agile methodology familiarity - Scrum, Kanban, or Earned Value Management for delivering security initiatives on schedule.
• Publications or community involvement - speaking at security conferences, contributing to open-source security tools, or authoring research papers.
• Hands-on penetration-testing / exploit-development experience with at least one of the following tools/frameworks: Metasploit, Cobalt Strike, Burp Suite, Immunity CANVAS, custom Python exploit frameworks.

Responsibilities

• Designing and implementing automated exploitation frameworks and test suites for novel cyber-engineering technologies.
• Conducting hands-on penetration testing, vulnerability analysis, and proof-of-concept exploits against prototypes and operational systems.
• Developing, executing, and maintaining functional, regression, and integration test cases to verify that software behaves as intended.
• Creating automated test scripts (e.g., using Python, PowerShell, or CI/CD tools) to increase test coverage and reduce manual effort.
• Tracking test results, logging defects, and coordinating mitigation activities with development teams.
• Documenting findings, generating actionable remediation recommendations, and presenting results to customers and senior leadership.
• Partnering with software engineers, system architects, and mission customers to embed security-by-design and quality-by-design principles early in development.
• Mentoring team members on exploitation techniques, software-testing best practices, and tool development.
• Contributing to a high-performing, innovative team environment that values curiosity, creativity, and a one-team mindset.
